I might have gone to the same college, in the 80s. I was a TA helping students punch FORTRAN on cards - already pretty obsolescent.

One thing about the CDC - it had perhaps the worst command interface I've run into. Data files were modeled as tapes, and you had to keep rewinding them.

Compiling a program appended to the object file, but running ran the start of the file, so you needed to rewind between, lest you run an old version. Much time lost trying to figure out why changes were ineffective.

FORTRAN variables had 8 significant characters, but the linker had only seven, so it was possible to get unintentional aliases.

As a grad student, I got to use a VAX.
